DIY Wall Chaser From Angle Grinder Dust Free

How to make a wall chaser from an angle grinder

Those who are engaged in electrical engineering, pipe laying, and other communications know how difficult it is to make strobes with an ordinary puncher. Not only do they turn out to be curves, but it also takes several times more time than when using a wall chaser.

However, not everyone has a wall chaser. But its manufacture from an angle grinder is not difficult. Plus, a homemade wall chaser can be connected to a construction or home vacuum cleaner, and then it will turn out to cut chases without dust and a respirator.

What is required to make a wall chaser

A factory wall chaser has almost the same design as a homemade one from an angle grinder. Here, too, the main element, cutting concrete and brick, are two diamond discs, which are spaced from each other by the distance necessary for cutting the grooves.

In the case of making a chasing cutter from an angle grinder, the kerf width can be adjusted with a nut, using one or two to insert between the discs. The only limitation in this case is the length of the shaft for an angle grinder for mounting discs. However, as practice shows, the length of the shaft is enough to make a wall chaser.

Now it remains to resolve the issue with the removal of dust. And here the sewer outlet from the 50 pipe comes to the rescue. Having made a slot in the branch for the discs so that they can rotate normally and, screwing the branch from the bottom of the angle grinder, it will be possible to connect a pipe or flexible hose from the vacuum cleaner to it.

Do-it-yourself wall chaser from an angle grinder

So, to make a homemade wall chaser from an angle grinder you will need:

• An additional nut for an angle grinder that allows you to attach two discs to the mounting shaft. It is very important that the discs are located opposite each other as evenly as possible, otherwise it will be dangerous to work with a homemade chasing cutter;
• Sewer pipe bend, which must be secured with a clamp at the bottom of the angle grinder. It is in the outlet that all the dust from the cutting of the strobe will fall, after which it will be pulled out with a vacuum cleaner;
• Two identical diamond blades for concrete that would fit an angle grinder.

The assembly of a wall chaser consists of several stages. First, you need to fix the first disc on the angle grinder rod by tightening it with a nut for this purpose.

Then the second disc is installed on the concrete, which is also attracted by the nut. When installing discs, pay attention to which direction they will rotate.

Attention! If the length of the rod of the angle grinder is not enough to install two discs, then it is better to refuse to manufacture a wall chaser. Otherwise, its design will pose a great danger. You can solve the problem by installing nuts of a smaller thickness or several, adjusting them to the desired size.

A sewer outlet, which will serve to extract dust, is installed from the bottom of the angle grinder. Before installation, you need to make a small cut in it, across the width of two discs. Thus, so that the dust directly falls into the outlet, and only then, it freely goes into the working vacuum cleaner.

Manual

A hand tool usually has a curved or straight handle. The straight handle chaser has two handy holders to cut straight and even grooves on vertical walls.

The curved-handle furrow cutter also has two convenient holders, but it also has a double-sided cutter, tightened with a bolt. This hand tool is used to create grooves of the desired depth and size in horizontal construction surfaces.

Tools and materials

To make wall chasers, we need:

• Fittings or plumbing pipe;
• Welding machine;
• Angle Grinder;
• Drill;
• A metal sheet;
• Two diamond circles.

Drill wall chaser

A drill is the most optimal and safest tool that can be used to make grooves and grooves.

• In order to make a wall chaser yourself from a conventional drill, you just need to fix a cutter of the required size in its chuck.
• With such a tool, you can easily cut grooves and grooves without the use of additional devices. But meanwhile, the groove turns out to be of insufficient quality, since the walls are not too even and not of the same depth.

It is a powerful tool that has two rubber rollers to help the chaser move easily over the wall surface to be treated. This furrower is equipped with comfortable grips and multiple incisors that are driven by an integrated electric motor. Designed for cutting grooves in various hard building materials.

This is a fairly simple construction tool, but its use from the master requires certain skills and work experience. Also, when working with a power tool, you should remember about personal protective equipment, as it creates a lot of construction dust and noise.

What is a wall chaser

A wall chaser is a tool that is designed to make grooves or grooves in various building blocks. Such grooves are necessary in order to hide all electrical wiring and other utilities during the construction of the walls of the house.

Manual wall chaser

Such a wall chaser is a versatile tool that performs all manipulations solely due to muscular strength. The principle of operation consists in manual cutting of a furrow with a working element. Therefore, its use is advisable where it is necessary to groove relatively soft coatings and materials. For example, on walls made of aerated concrete or adobe, such a device will easily make the necessary recess, but on a brick or cinder block it will be completely ineffective.

Factory models of manual wall chasers are relatively inexpensive, but if you have a welding machine at hand, an angle grinder with a diamond disc (hacksaws) and a suitable material (pipes, fittings, sheet metal), it is much faster to make them yourself.

For this:

• Cut a piece of reinforcement or pipe to the length you need. it should take into account the handle and the work area or place for its attachment;
• Bend the edge with a vise or some kind of lever. the handle should be as comfortable as possible, otherwise the hand will slide off when pressing on the chaser; Fig. 2: fold the edge with a vise
• Cut a piece of rebar or pipe for the second handle;
• Weld the second handle at a convenient distance. it should be located closer to the working element, so you will need to apply less effort when chasing; Fig. 3: weld the second handle
• Cut the working edge of the pipe at an angle of 45º or less, ensuring sufficient width of the working element;
• If you want to make a movable working element from a strip of metal, bend a steel strip 2. 3 cm wide in the shape of an oval. 4: Bend the steel strip
• and fasten it with a bolt or welding on the edge of the pipe or fitting.

The wall chaser is ready, with the help of such a manual device you can perform the whole range of works. If the volume of chasing is large enough, be sure to use working gloves or put pieces of rubber hose on the handles so as not to rub your palms.

How to make a wall chaser with your own hands?

During repairs or any construction work, many are faced with the need to lay wiring and other communications (water pipes, sewers, etc.). These mowing lines are an integral part of a modern home, but their outdoor installation greatly degrades the interior of the room, which is why they try to hide them, as a rule, in a special ditch. Due to its high cost, it is impractical to purchase a factory tool for these purposes, therefore many are wondering how to make a wall chaser with their own hands from scrap materials. Otherwise, you will have to carry out all the work with a hammer and chisel, which will significantly complicate the process and require much more time.

Electric wall chaser

An electrically powered tool is much more efficient at making a groove in a wall. Therefore, for durable surfaces and large volumes of work, it is much more convenient to use a ready-made tool for making an electric wall chaser. The most suitable option for an electric tool is a conventional angle grinder, which lacks one more working disc to function in the chasing mode.

In practice, this issue can be solved quite simply:

• Purchase two identical concrete discs and an additional tightening nut;
• First, install one disc on the angle grinder and tighten the native nut, as in normal operation with an angle grinder; Fig. 5: install the first disc on the angle grinder
• Place the second disc over the nut on the shaft; Install the second drive
• Press the second disc with one more nut; Fig. 7: press down the second disc with a nut
• Electric wall chaser ready to use.

It should be noted that in some models of angle grinder the shaft length can be very short, so after installing the second disc, there will not be enough space to tighten the nut. In such situations, it is necessary to install between the discs instead of the clamping nut a piece of pipe or washer separating the discs. This will significantly reduce the width of the groove, but will allow both discs to be secured at the same time. If there is sufficient shaft length, similar spacers can be used to increase the width of the groove, for example, for water pipes or for several cables.

The only drawback of such a home-made tool will be a huge amount of dust when developing furrows in the wall, since structurally, an angle grinder, unlike a chasing cutter, is equipped with a shield only from flying particles. Therefore, during long-term work, you will need to protect the organs of vision and respiration. To do this, you can use both a respirator in combination with goggles, and a special cover in combination with an industrial vacuum cleaner. The first option is the simplest, but the dust will settle all over the room and create a number of difficulties, for the second you will need a construction vacuum cleaner and a dust collection hood.

Homemade cover for wall chaser.

Due to the fact that the original casing for a wall chaser costs a lot, it is much more profitable to make it yourself from scrap materials. Structurally, a homemade casing should have an outlet for connecting a hose from a vacuum cleaner. A conventional vacuum cleaner will not cope with such a volume of debris and its fractions, as a result, the bag or flask will fill up too quickly, and the motor may break down from fine dust. Therefore, you will need to rent such a device or convert an existing one.

The simplest way to make such a nozzle for a wall chaser is a plastic eggplant, in which the bottom is cut off, and a vacuum cleaner hose is connected to the lid. Such a device will not last long, but you should have enough to work in one room. If you need a wall chaser for an entire apartment or house, make a more durable and reliable metal casing.

For a metal casing, you will need a steel sheet 1. 2mm thick. angle grinder with diamond disc, welding or screws with sealant (depending on the convenient mounting method). If the metal is too thin and it will not work to take it for welding, then it is better to connect the parts of the nozzle with bolts and treat it at the seams with a sealant. Since the welded structure is more reliable, we will consider this option in detail.

The whole process of making a homemade wall chaser bit consists of the following steps:

• Draw a drawing of the future casing for the wall chaser, you can make a template for cutting out the side elements;
• Cut out two side pieces, in one of which make a hole for the angle grinder shaft; Fig. 9: side plate with hole
• Using a metal strip, connect the two parts by welding, file all irregularities in the seams with a file so as not to hurt yourself during work; Fig. 10: use a strip to weld the side pieces
• To the outer edge of the chasing nozzle, weld a branch pipe suitable in diameter for connecting a vacuum cleaner; Fig. 11: weld the pipe
• Weld two metal bars along the edges of the wall chaser attachment, make holes in them for attaching the casing to the angle grinder; Fig. 12: Weld the clamp
• Weld a clamp on two clamps to a separate metal sheet of a triangular shape, as shown in the figure. it is designed to grip an angle grinder and allows you to adjust the depth of chasing.

Perforator

Another common and fairly simple way to make a wall chaser yourself is a hammer drill. But instead of the usual drill, a cutter of the required size should be inserted into it.

Such a chasing cutter is quite simple and does not require a lot of time and effort for its manufacture, but, at the same time, it gives a very low quality of work. The groove is obtained not only with a curve in height and length, but also with different depths and widths. As a result, you will have to spend much more time chasing and much more finishing materials.

Making a wall chaser attachment for an angle grinder with your own hands

When using an angle grinder as a chaser, it must be borne in mind that this tool is not at all intended for use with two discs. The presence of two discs in the spindle of the angle grinder doubles the load on the electric motor, so it overheats faster and may fail if you do not pause in a timely manner. It is especially necessary to abandon the idea of ​​using two discs in the spindle of a power tool if a household or amateur angle grinder is used. In such a tool, not only the electric motor will fail quickly, but also the gear pairs.

If it is decided to make a two-disc chaser from an angle grinder, then this can be done as follows:

• The first circle is fixed in the spindle using a standard nut. The second disc is secured with a nut from the roughing disc
• It turns out a small distance between the circles, but it is quite enough to get a groove in which the electric cable will be laid
• If it is necessary to get a larger groove, then to implement the idea, washers are used, located between the discs.
• The standard thread length is insufficient to place the discs at a distant distance from each other, therefore, for this, you will need to use the method of manufacturing the extension sleeve. It is not difficult to make it, for which you need a wide nut, one part of which is screwed onto the standard thread of an angle grinder, and a threaded extension is screwed into the second. At the same time, it is important to choose an extension cord from high-quality materials so that it does not collapse during the work.

Having figured out how to fix two discs on an angle grinder with your own hands, it remains to find out from what and how you can make a nozzle for a wall chipping tool. Such a nozzle is also called a cover, which is an obstacle to the ingress of concrete particles onto a person, and also prevents the formation of dust and debris. Usually, such covers are made with a special hole and a round fitting for connecting a hose from a vacuum cleaner.

Angle grinder attachment wall chaser DIY production

To lay communications in the walls, you will need the use of a specialized tool. a wall chaser. It is rational to buy it for professionals who are engaged in repair and construction work, in particular for electricians, plumbers, plumbers, etc. If the repair is carried out on your own in a house or apartment, then it is not necessary to buy a specialized tool, since you can make a wall chaser attachment for an angle grinder. How this can be done with the least investment is described in detail in the material.

What to make a protective dust cover for an angle grinder

The manufacture of a protective casing involves the use of such types of materials as a plastic canister, pots made of aluminum, chipboard, plywood, laminate, board, stainless steel sheets, etc. You can choose any material that is available on the farm. This eliminates the need to buy a nozzle, since it is very easy and simple to make it yourself.

The main condition is to ensure sufficient strength of the finished angle grinder attachment. The casing must withstand the impact of small concrete particles flying out during work. To make the casing, there is no need to resort to the use of auxiliary tools, such as welding, since a nozzle can be quickly made from a plastic canister. An example of such a nozzle is shown in the photo below.

It takes a minimum of time to make such a device. A homemade wall chaser from an angle grinder can be made quickly and easily using an arsenal of available tools. If you use materials made of aluminum or wood, then when working on the manufacture of the nozzle you will need self-tapping screws, and when using steel you cannot do without a welding machine. Consider the principle of making a do-it-yourself wall chaser attachment for an angle grinder:

• For manufacturing, you will need leftovers from chipboard or fiberboard. In addition, even plywood is suitable, so we use any sheet material that is available
• Two side bases are cut out of the chipboard of the corresponding shape. The shapes of these bases depend on the dimensions of the available tools.
• In order not to have to select a shape, it is recommended that you first make a drawing on paper, and then transfer it to cardboard. Make a template from cardboard, eliminating all the shortcomings
• Based on the template, make a cover using chipboard for this
• Drill a hole of the appropriate diameter on one side of the chipboard base. Use this hole to secure the finished accessory to the power tool.
• To connect the chipboard in the manufacture of the nozzle, you can use self-tapping screws or special furniture fasteners of the appropriate length

The photo below shows the resulting cover for an angle grinder. Such a cover is easy to make, but its disadvantage is the absence of a hole for connecting a hose. To eliminate this drawback, a sleeve of the appropriate diameter and length will help, which must be installed in the upper part of the structure. Connect the hose from the vacuum cleaner to the protrusion of the sleeve.

The process of making a nozzle is not difficult, and the quality of the final device depends more on the ingenuity and imagination of the master. You can make with your own hands not a simple cover for an angle grinder, but also adjustable. The principle of manufacturing an adjustable protective casing is that you need to make an additional movable part. Due to this movable part, the required size of the projection of the cutting discs on the angle grinder will be selected.

In a similar manner, you can make a nozzle with an adjustable part from chipboard and other materials.

The purpose of the chaser what can you do with it

A highly specialized tool called a chasing cutter bears similarities to an angle grinder or, in a simple way, an angle grinder. A wall chaser, unlike an angle grinder, is designed directly for making grooves in walls with further laying in them of various communications, such as wires and cables, water and sewer pipelines, as well as other devices.

The wall chaser has two parallel disks on concrete, the distance between them can be adjusted depending on the technological task. This allows you to prepare a groove in the wall of the required width. This highly specialized tool also has a groove depth adjustment function. The required value of the groove deepening is selected due to the movement of the cutting discs, and depending on the technological task.

A wall chaser is quite expensive, and it is used exclusively for wall chasing, so not everyone can afford such an acquisition. In order not to have to buy a highly specialized tool, you can make it yourself from an angle grinder. The construction of a wall chaser is similar to an angle grinder, so it is rational to use an angle grinder to make a tool for making grooves in the wall.

The inconvenience of using an angle grinder as a chaser is that the skill of the worker is required to adjust the depth and width of the groove. A special self-made casing will help to replace this skill, as well as to simplify the process of wall chipping at the same time. A special cover for an angle grinder allows you to get the following advantages:

• Savings on the purchase of a specialized tool
• Ease of work
• Dust-free grooving work in residential and non-residential premises

In addition to a specialized wall chaser, you can make a groove in the wall for laying communications using the following tools:

• angle grinder or angle grinder of different brands
• Perforator
• A hammer with a chisel is the simplest and most economical option, but the rationality of its use is determined by the amount of work planned

Wall gouging angle grinder or the effectiveness of this tool

You can make a channel with an angle grinder in walls made of materials such as brick, concrete, cinder block, tiles, tiles, and other types of materials. For crushing these materials, specialized nozzles are used. diamond-coated disks. The process of how to make a strobe angle grinder consists in performing the following actions:

• Marking is the most important part of the work, which consists in drawing lines with a marker or pencil on the surface of the wall. For marking, you will need a pencil, tape measure, as well as a rule or a water level. When marking, it is necessary to make the mowing line thicker so that when the cutting tool is moved, they can be seen
• Cutting a groove. consists in “passing” the tool along the lined lines. The tool should be held firmly and moved slowly. In this case, it is important to wear special protective equipment such as glasses, respirator and gloves.
• Making a channel. after cutting the lines with the cutting disc, you will need to cut out the remaining concrete. These residues should be removed with a chisel hammer or puncher.

How to make a Wall Chaser using an Angle Grinder

You can attach two discs to an angle grinder, just like on a wall chaser. This will allow you to do double work at a time. In one “pass” the instrument produces a finished channel. When working on making a neat channel, a large amount of dust is released. To prevent dust from settling in a room where repairs have already been completed, a special nozzle is used to which a vacuum cleaner is connected. The vacuum cleaner sucks up all the dust generated during the crushing of concrete.

What recommendations and tips to consider when chasing

You can start the procedure for preparing grooves in the room immediately after making a homemade product. When punching a groove, one important nuance must be taken into account. the work should be carried out in a room where the locations of the electrical wiring are previously known. If an energized wire is encountered on the path of the instrument, the result of such a meeting can be fatal for the master.

It is necessary to carry out chipping work both with a conventional chasing cutter and an angle grinder, taking into account the following tips and recommendations:

• The procedures can be carried out in vertical or horizontal directions
• It is possible to slant at an angle in extremely rare cases when it is necessary to bypass a decorative element or communications
• Horizontal slitting must be carried out only at a distance of up to 15 cm from the floor slab
• Vertical grooves should be located at a minimum distance of 10 cm from doors and windows
• When carrying out work, it is important to take into account the depth of the groove. It is necessary to choose the depth depending on the type of communications that are planned to be laid in the groove, as well as on the thickness of the wall itself. If this wall is load-bearing, and is external, then the depth of the groove should not be more than 3 cm
• The groove width is also selected depending on the technological task, but it is not recommended to exceed the permissible limit of 2.5-3 cm

After laying the communications, the groove should be repaired with cement mortar. The location of the groove should be leveled with the plaster of the wall. It is recommended that chipping works be carried out at the construction and repair stage before plastering the walls.

It is not at all difficult to make a wall chaser for concrete from an angle grinder, and if you set yourself such a goal, then everyone can achieve it. When drawing a conclusion about the work done, it should be noted that when chipping, you need to take breaks to allow the power tool to cool down. If the cover does not have a connector for connecting a vacuum cleaner, then work must be carried out in a respirator. Glasses must be worn in any case, as various small particles can enter the eye.

Depending on the type of material that is channeled, it is necessary to select the appropriate speed of movement of the tool. If you come across reinforcement in a concrete wall on the way, it is recommended to cut it with an abrasive wheel. It is necessary to use a wood chaser with extreme caution, not forgetting about the reverse impact.

Special features of the tool. how will it help us

When laying the elements of engineering communications (pipelines, various cables or electrical wiring), it is often necessary to groove new furrows for the wires for various reasons. To cut grooves in monolithic reinforced concrete walls and ceilings, in brickwork and other materials, you can use an angle grinder and a perforator. However, modern industry does not stand still. Every day more and more new devices are offered to the attention of professionals and amateurs to simplify construction and installation work. The wall chaser is no exception. a special tool for making channels in walls for wiring and other communications.

The principle of operation and appearance of a manual wall chaser is very similar to an angle grinder. They have very few differences between themselves:

• The wall chaser simultaneously makes two parallel cuts at once, since there are two cutting discs in its device.
• Unlike an angle grinder, the chaser is equipped with a working platform, which, when a certain depth of the slot is reached, abuts the surface, preventing the hole from deepening. This platform can adjust the groove depth due to its flexibility.
• Some types of wall chasers are equipped with a dust removal system, which is very important for construction work.

The principle of operation of the wall chaser is as follows: when using this tool for marking on the surface, rotating diamond discs cut two parallel grooves.
The plaster between them is removed with a hammer drill or manually, with a chisel and hammer. Thus, a groove of the desired size is obtained. When using an angle grinder (angle grinder), the work is done much longer, moreover, it is not very convenient to maintain a constant slot depth with an angle grinder in hand. Stroborez was created to increase the speed of work with a large-scale device of hidden communications.

Homemade wall chaser with your own hands. what to assemble from and what you need to know?

Elements of utilities are rarely used as decoration. Pipes, cables and wires are usually hidden, since they can be accidentally damaged in the public domain. To protect communications, boxes, cable channels and other elements (corrugations, plinths) are used. According to modern standards, it is recommended to lay pipelines and cables in a hidden way.

To make channels for wiring and pipelines, a special tool is used. a wall chaser.

How to make a wall chaser from an angle grinder with your own hands: step by step

A wall chaser is a very useful tool, but few people acquire it specifically in order to make repairs in the house. This is not a justified investment, because its cost is quite high. In this case, you can do it yourself, especially if you have an extra angle grinder available.

To make a homemade wall chaser from an angle grinder, you first need to prepare everything you need: a pair of diamond discs, an angle grinder, nuts, a protective cover or metal for its manufacture (an old pan is fine), a vacuum cleaner. The main difference from an angle grinder is the presence of two cutting diamond discs, therefore, in order to make a chaser, it is necessary to adapt it to two cutting elements:

One of the discs is attached to the machine in the traditional way.

To mount the second disc, you will need a securing nut with an additional ring of the same diameter as on the main nut.

The remaining disc is placed on the nut that secures the first disc, and is fixed with an additional nut, turned upside down. It is important here that the remaining thread is sufficient to secure the cutting element.

If you install a distance sleeve or an elongated nut between the cutting elements of the chaser, this will allow you to change the distance between them during the operation of the tool, eventually adjusting the width of the groove being cut.

Many amateur craftsmen still have a lot of, though old Soviet, but still serviceable radio elements, which will come in handy for a soldering station circuit. A useful article will help you make such a tool yourself from scrap materials.

The return springs can be made from steel wire.

The structure must be pre-assembled, eliminated if any defects, disassembled and painted.

The resulting dust can be sucked in by a vacuum cleaner operating in parallel with the chaser or by a vacuum cleaner motor attached directly to the chaser. The motor should be attached to the tool in such a way that it is convenient to hold the wall chaser during work.

To operate a self-made wall chaser, you will need two sockets: for connecting a tool and a vacuum cleaner.

The advantage of using a do-it-yourself wall chaser is that this tool is a more economical option in terms of wasting it. In addition, using a wall chaser instead of an angle grinder significantly reduces installation time. Thanks to the chasing cutter, a perfectly even seam is obtained for laying cables, up to 30mm wide. For wider furrows, you can use the wall chaser twice or more in parallel.

Design features of an industrial wall chaser

• The orientation of the cutting nozzle is strictly perpendicular to the sole;
• Possibility of installing two discs at a fixed distance from each other (determined by the width of the groove);
• The presence of a sole that easily moves along the wall to be treated. As a rule. equipped with casters;
• Using the sole settings, you can fix the depth of the groove;
• Necessarily equipped with devices for removing dust from the working area.

All these qualities make working with the tool easy and efficient, if not for two disadvantages:

• The high cost of the appliance;
• Narrow specialization.

For the construction crew, this is a justifiable expense. And if you, as a home craftsman, need to make strobes once every few years, buying such a specialized tool is too burdensome for the budget. over, it is unlikely that a wall chaser will be able to find another application.

There is an exit. Making a rarely used but useful device with your own hands.

Step-by-step instructions for making a high-quality casing for a wall chaser from an angle grinder

The material used is an iron sheet of 2-3 mm. Aluminum can be used, but it is more expensive to weld and its strength is lower.

Having decided on the width of the working nozzle, you can calculate the required distance between the “cheeks” of the casing.

If the movable part of the structure is inside (and this is the optimal layout), then the minimum width is determined by it.

A clamp is attached to the outer wall of the casing to fix the angle grinder. Special attention must be paid to the strength of this knot. At least 50% of the circumference must be welded, and with a continuous seam. If the casing falls off the angle grinder due to vibration, the disc will jam with all the ensuing consequences.

On the side wall there is a branch pipe for attaching the handle.

All structural elements are modeled from cardboard, cut from metal by the same angle grinder, and welded together. After processing, it is better to paint the parts with durable paint.

In the upper part we install the nozzle for the vacuum cleaner.

The sole provides for fastening for guide rollers, an angle grinder is made along the axis of movement. The critical unit will be the retaining guide for the upper part of the casing. A threaded rod is placed on its end to fix the position of the cutting depth.

If there is a need for smooth immersion of the discs into the wall, for example, when working on reinforced concrete, return springs can be provided.

This design is absolutely safe, allows you to control the depth and width of the furrow, and ensures a clean workplace.

In this video, the master tells how he made a chasing cutter with two discs from an ordinary angle grinder.

Homemade wall chaser

This is not about creating a mechanized device from scrap materials. over, this tool belongs to the category of dangerous, and there is no reason to put yourself at risk.
You can purchase an attachment for an angle grinder, it is not so expensive. And there is an angle grinder in almost every house where renovations are planned.

However, such a nozzle still costs some money, and does not allow the master to realize his creative potential. Not to mention, the cover limits both the width and the diameter of the chaser discs.

• The simplest chasers

When building a house, or carrying out large-scale repairs, it is often necessary to cut walls. Saws are necessary for laying electrical wiring, hidden laying of heating or water pipes, and other needs.

Previously, home craftsmen hammered the grooves with a bolt or a perforator, which took a lot of time and effort, and the groove turned out to be far from ideal. a lot of material was spent when plastering.
Manufacturers of power tools quickly got their bearings and issued a wall-mounted chaser. A kind of symbiosis of a circular saw and an angle grinder, capable of walking several meters of a wall of any strength, from brick to reinforced concrete, in a matter of minutes.

The principle of operation is as follows. two working discs (depending on the hardness and strength of the wall, different materials are used) cut parallel slots of a given depth, which are then easily knocked out, turning into a groove.

How to make a full-fledged wall chaser from an angle grinder

The easiest option is to install a second disc using a combination of standard nuts angle grinder.

The first disc is installed on the working shaft. It is fixed with a standard nut, and is a spacer sleeve between the cutters. The second disc is secured with a roughing disc nut (usually included with an angle grinder). The second nut is screwed upside down.

With a sufficient length of the working shaft, you can adjust the distance between the cutting discs using shims, or make an adjusting sleeve. Then it will be possible to cut grooves of different widths, for wiring or for laying pipes.

Therefore, it is necessary to periodically take a break to rest the engine and protect it from overheating.

This design is easy to manufacture, but does not solve the main problem that arises during operation. dust and stone fragments.

When used indoors, the tool must be equipped with a dust cover and dust extraction system.

The chaser vacuum cleaner should be of the cyclonic type, since the conventional design with a trapping filter will quickly become clogged with stone cut products and the air extraction performance will decrease.

With a small amount of work, as well as in the case when construction is underway, and there is no danger of contamination of the interior decoration of the room, you can limit yourself to the simplest casing of the required size. It will not solve the problem of dust formation, but will protect the work area and the operator from the scattering of cut products. The casing can literally be made from construction waste. for example, from pieces of laminate or plywood. The design is simple, free, but effective.

The only drawback of this solution (in addition to dust) is the impossibility of quickly adjusting the depth of chasing. However, for cuts of the same type (for example, laying electrical wiring throughout the house), the depth does not need to be adjusted. No guide wheels required, the wooden surface of the casing glides gently over the concrete as the tool moves.

In order to increase the efficiency of work, some effort should be made, and a full-fledged casing with a furrow depth regulator and a pipe for dust extraction.

In such a design, it is possible to provide for both the width of the chasing and easy movement along a rough wall using the guide wheels.

The simplest chasers

The most primitive is the construction of aerated concrete furrow cutter. The material is so malleable that it can be processed like butter or plasticine.

Therefore, the power tool is not needed, all the grooves for the foam blocks are cut by hand, without dust and unnecessary debris. Of course, such a device can be made independently.
